TQALL WHOM IT MAY eoncmtm Be itknown that. I, C. CQSIIRBMME, of.the city of Austin, in the county of Travis, in the State of Texeg have invented n New Mode of Vitreogrnphy, and do .herc'by declare that the following is a i'nllandexact descri tion thereof. 7 v V The nature of my invention consists in applying to-the ground surface of glass or I other similar material, a

sum solution of glue or other stioky mstter, -'snoh as paste, mncilag'e, white'of eggs, &c., which, in the process of drying-and hardening, contracts, and thus deti'rches. and brings away, when removed, particles from the sub fic'e ofth c glass where applied, leaving the part which isooveredto look like ice or frozen snow, thus producing ornamental figures or designs ol'any description desired upon glassn'.

I proceed now to describethe modes of application to produce this effect. I.will suppose it to'be n. pane of window glass which is to be ornamented, which will answer for everyother c'ase as wellf After-the desired figure orornament is designed on pnper,'the pane may be placed over it, ground side upwards, and the lines of the figure trnced on it with n pencil. Then a coat of vsrnish is applied to the whole surface of the glass; except that covered by or embraced withinthe v figure, which is. tobe left free from the varnish, and when this (the varnish) is: su-fiioiently dry and hard, the glue is to be nppliedwltli a'brush freely over the figure or portion of. glass not covered by the varnish, and may be done in a hasty manner without reference to the lines of the figure, the varnish being a perfect protection to the glass from the hction of the glue, nnd leaving it to take eii'ect only on'the-expcsed glass embrnccdwithin the figure. The varnish, which adheres to the gloss with less tenacity than the glue, always gives way when forced by the contraction of the glue without injury to theiglass, preserving its snrfaice from any cha nge by the action of the g lue 'yand iitit should be necessary to make in any case a second application of glue, care must be taken to repair any injury which may hsve happened to the-coat of varnish. The glue, by its own action in contrscting, springs offwith the detached particles of glass, andleaves then nothing to be done but to remove the vsrnish. by dissolving fluids. The mode here described may be simplified to agreat extent by using patterns in applying thevarnish, either in the manner of bru'shing through or 'printing on the glass the protecting varhishy which hitter method would also be applicable in certain cases, even in transferring the glue, when the varnish n'ould be dispensed with altogether. It will be understood that tho figures produced may be either of the portions of the glass acted upon by the glue; omof the smooth ground surface of the glass, by causing .the action of the glue upon every portion of it except the'figure. it will be seen that this kind of vitreographymay be 'edvnntageouiy applied to objects where brightness :shd lustre are most valued, as for instance on lamp-globes and cylinders, on glass drops and han'gings'for girandoles, he to window panes designed for decoration or to screen from observation while at the same time admitting light. I am aware of the existence of ornamented glasses similar in general appearance and produced for the samepurposes, but by modes essentially different frommine.

What I claim as my invention, -is--. The 'inode of ornsmentin'g glass as herein described, by the-application of glue or similar ldhesive and contracting matter, and in this manner recise modlfls for cas'tigg all on every kind of ornamental glass and A1 of which I ra that otters stsutms e rants me. glass ware, and for l p y y g C. c. STREMME.
